Possible Causes
Weak Wi‑Fi signal at dock, Incorrect Wi‑Fi password or band, Faulty Wi‑Fi module on main board, Router blocking device
How to Fix / Troubleshooting
Safety first: There is no electrical hazard in network troubleshooting, but avoid opening the robot for this issue.
- Check Wi‑Fi band: Ensure your router's 2.4 GHz band is enabled; many robot vacuums, including Wyze, do not support 5 GHz for setup.
- Move dock closer to router: Place the charging dock within a reasonable range of your router to improve signal strength.
- Reset network settings: Use the Wyze app or robot button sequence (per manual) to reset Wi‑Fi settings, then re-add the robot to the app.
- Verify router settings: Disable MAC filtering or add the robot's MAC address to the allowed list. Ensure the SSID is visible and not hidden.
- If C15 persists with strong Wi‑Fi: The internal Wi‑Fi module or antenna may be faulty. This is integrated into the main board on most Wyze models and requires board replacement by Wyze or a professional.
